Transport error failure with return code 12

Question

Hello Experts
I was trying to transport a request which consists of four Cubes, Infosources, datasources, Update rules and communication structure from QA to Test. The transport went without any problems from Dev to QA. However, while transporting to Q, it finished with errors with return code 12 with the following error: I tried to import it thrice with no success
Program terminated (job: RDDEXECL, no.: 21120900)
I checked in SM37 and the background job for this transport gets terminated everytime with the following dump:
Error analysis                                                                               
An exception occurred which is explained in detail below.  The exception, which is assigned to class 'CX_RSR_X_MESSAGE', was not caught and therefore caused a runtime error. The reason for the exception is: No text available for this exception   
Does anyone has a clue about this?
Thanks

Hi Rishi ,
The Issue may be with the buffer capacity while transporting .
As i see from the post that you have captured all the objects
in one request and sent to target system . As per my experience never include all the objects in one Request .
Try to separate them depending on the onject types ,i mean datasource , infosource , ODS & cube seperately .
IF you cannot solve the problem , i think it is better to create a new request as i said in Development and try to move them to production .If next time request fail then you can look at the only that particuler Request only .
IF you have more information please share .
Thanks
